In addition to absorption by hemoglobin, refraction and reflection (ie, scattering) of the light
beam also occur within tissue beds. Scattering at the interface of red cells and plasma may …

Background: Nutrition informatics has become a novel approach for registered dietitians to
practice in this field and make a profit for health care. Recommendation systems considered …

A new type of touch sensor for detecting contact pressure at human fingertips is presented.
This new sensor allows the fingers to directly contact the environment without obstructing the …

This project had two main objectives. The first of these was to design and construct a
spectroscopic instrument to monitor small changes in optical transmission across an infant's …

An improved pulse oximeter (sensor and monitor) uses a plurality of wavelengths selected to
provide sensitivity to both oxygen saturation and deviations in tissue site characteristic (s) …

The backscattered and transmitted diagrams of He–Ne laser light illuminating a
concentrated suspension of red blood cells (RBC's) are investigated. The shapes of these …

Photon-diffusion theory has had limited success in modeling the optical transmittance of
whole blood. Therefore we have developed a new photon-diffusion model of the optical …

A method and apparatus for noninvasively monitoring hemoglobin concentration and
oxygen saturation, wherein the method includes selecting at least two wavelengths from a …

Transmission and reflectance are the two main modes of pulse oximetry. In obstetrics, due to
the absence of a transilluminable fetal part for transmission oximetry, the only feasible option …
